Age-group differences in trust-related decision-making and learning.

Facial impressions contribute to evaluations of trustworthiness. Older adults are especially vulnerable to trust violations, incurring risks for deception and exploitation. Using the newly developed social Iowa Gambling Task (S-IGT), we examined age-group differences in the impact of facial trustworthiness on decision-making and learning.

Aging in an "infodemic": The role of analytical reasoning, affect, and news consumption frequency on news veracity detection.

Increasing misinformation spread poses a threat to older adults but there is little research on older adults within the fake news literature. Embedded in the Changes in Integration for Social Decisions in Aging (CISDA) model, this study examined the role of (a) analytical reasoning; (b) affect; (c) news consumption frequency, and their interplay with (d) news content on news veracity detection in aging. Conducted during the early phase of the COVID-19 pandemic, the present study asked participants to view and evaluate COVID or non-COVID (i.

Chronic oxytocin administration in older men modulates functional connectivity during animacy perception.

While aging is associated with social-cognitive change and oxytocin plays a crucial role in social cognition, oxytocin's effects on the social brain in older age remain understudied. To date, no study has examined the effects of chronic intranasal oxytocin administration on brain mechanisms underlying animacy perception in older adults. Using a placebo-controlled, randomized, double-blinded design in generally healthy older men (mean age (SD) = 69(6);  = 17 oxytocin;  = 14 placebo), this study determined the effects of a four-week intranasal oxytocin administration (24 international units/twice a day) on functional MRI (fMRI) during the Heider-Simmel task.

CISDA: Changes in Integration for Social Decisions in Aging.

The aging of our population has been accompanied by increasing concerns about older adults' vulnerability to violations of trust and a growing interest in normative age-related changes to decision making involving social partners. This intersection has spurred research on age-related neurocognitive and affective changes underlying social decision making. Based on our review and synthesis of this literature, we propose a specification that targets social decision making in aging to the recently proposed Affect-Integration-Motivation (AIM) framework.

Systemic Inflammation Mediates Age-Related Cognitive Deficits.

The association between systemic inflammation and cognitive deficits is well-documented. Further, previous studies have shown that systemic inflammation levels increase with age. The present study took a novel approach by examining the extent to which systemic inflammation levels mediated age-related cognitive decline.
